To all whomit may' concern lBe it known that 'I JULiUs BRENZINGER, a citizen ofthe United States, residing at Fairfield, in the county of lFairfield and State of Connecticut, have invented certain new and useful Improvements in Assembling and Feeding Devices for Gan-Heading Machines, iication. e

This 'invention relates generally to can heading machines, with more particular reference .to accessory, adjunctive or ap-l /purtenant mechanisms for automatically advancing lled or packed open cans and the can tops or covers in succession and delivering the same in properly assembled condition for the heading operation in the seaming mechanism. l

As is well known in what may be termed the can heading art, one of the nlore serious difficulties encountered in attempting prof vide a device ordevices for automatically fact that inthe assembling the unseamed can parts and delivering the same in assembled`condition to the seaming mechanism of a heading ma chine, is that which i's attributable to the packaging of many kinds of perishable food larger fruits, it is almost invariably necessary to more or less over-fill the can in order to insure the desired weightv or bulk of con tents when the top or cover is pressedto position lfor seam-ing and retainthesame in ysuch position ,until hermetic sea-ling `is effected, usually "by the wellknown doub/leseaming operation. In automatically -assembling body and top whenthecan has .been over-filled and then conveying the assembled parts to the seam'ing mechanism, it will beapparent, first, that it is by no means easy to perfectly' adjust a cover on an overfilled can, and,'second, vthat itis just as ar from easy vto'retainthe' loose cover in proper adjustment during transit 'of can and cover the seami mechanism.v lt will Ilslie cans and'covers are separately conveyed tothe seamin mechanism, and assembly take -place therein, where further movement of these parts prior tothe seaming operation isl in a verticalfdirection only, the diiiculty to which I have referred wil be minimized if not actually eliminated.

- which may be said to of which the 4following is a specierder to insure against prducts, particularly the gingand possibly the cover delivering mechanism,

Furthermore, if feedin 'and assembling u mechanism is desired whic is entirely 'automatic in its operation, 'there are two features vMi be of the greatestimn gortance. Such an inter-relationship should e established between the can feedin or advancing mechanism and the cover fee ing or .advancingmechanism that either thereof 80 will automaticallybecome inoperative upon inoperativeness of the other orfif :frany reason the other fails to Aperform its function. In other words, first, should the supply of covers become exhausted, and therefore .no cover be .in position -for delivery to the can body next to be advanced,'the can feeding or advancin mechanism should at once automatically come inoperative, in

a useless seaming ,operation en an open or uncovered can withvprobable spilling 4of the vcontentsthereof and conse nent waste, to

' say nothing of a- Ifanifestly o jectionable be smearing ofithe machine parts; and,.second, '75- should no can be positionedin or on the con` veying or advancin means .for next' succeeding delivery to t e seaming mechanism, 'the coverV delivering mechanism should at once automatically ,become inoperative, `or operatively ineffective, so that no cover will be carried by itself into the seaming mechanism and be distorted to the point of clog? even cause breakage of parts of-the. machine. chine should loperate on the principles of Jno can, n oRcover,`-and no cover, no caii..

An inf ortant object of the present invention ist-,lie ovision of an' improved ma chine in which the can bodies and the tops .9,0 or covers therefor are separately conveyed h to the sc aming mechanism, whereinthey are" properly assembled -for' successiveseaming f v have 'referredv betweenthe' can' advancing mechanism andl wh'ereby'no` ,cover is deliverec'l` when (a can -bo'd in osition to receivejthesame,;an nocan '1500 bodyl advancedwhen'a cover is notl being delivered for superposition vl`thereon. l jIneidental to the '.'above, 'I have. in view a nifachine of the character outlined-which, con-. 1

There are many different types of can heading or so-called double seaming machines, with any one of which the feeding and assembling device of the ypresent invention might doubtless be successfully employed. For purposes of illustration and description, however. I have shown in Fig. 1 a well-known type of double'seamer and one for use in connection with which my improved assembling and feeding device is particularly weli adapted. This machine comprises the usual standard 21 with its heavy supporting base 22 and the overhang 23 assembled parts against the centripetal forces of the seaming operation, which 1s mounted at the lower end of a vertically reciprocating rod or stem 25, and scanning rollers 26 mounted to be revolved around the chuck and be brought intermittently into effectively coperative positional relation to the working or peripheral edge of said chuck to intercurl the superposed flanges on can body and cover in performing the well-known double seaming operation. The seaming mechanism is driven from the main driving shaft 27, suitably journaled in the vertical portion of the overhang 23, carrying the usual fast and loose pulleys 28 and 29 and connected in the usual manner with any suitable source of power. The specilic means shown in Fig. 1 for operating the seaming rollersA and chuck are clearly shown and described in detail by me in my prior latentsNos. 1,167,316 and 1,167,317, both granted on January 1, 1916. lt is also to be understood that l prefer that the seaming mechanism. properthat is to say, the. seaming rollers and vthe chuck-be brought into effectively coperating positional relationship only when a can body with its superposed cover is positioned in the seaming mechanism, and 1 have shown means for this purpose which is shown and described in detail in other patents, such as my Patent No. 1,167,212), and, more particularly, No. 1,167,351, both granted to me on January l, 1916. i For the purposes of this description, therefore, it will doubtless suilice to state that when a can body is delivered to proper position on the vertically reciprocable platform 30, with a top or cover positioned above the same, and said platform is raised to assemble can body and cover and clamp the same between said platform and the chuck 24, the can is headed in the usual manner and delivered upon the chute 31 for conveyance to such destination as may be desired.

As hereinbefore stated, the present invention has only to do with means for automatically successively delivering to and positioning in the seaming mechanism can bodies and covers, and in connection therewith the establishment of an inter-relationship between the can-feed and the cover-feed mechanisms that the operation of either thereof is dependent upon effective operation of the other.V i d There are undoubtedly a number of wellknown ways of delivering can bodies to and positioning the same in the seaming mechanism. It. may be assumed, however, as a general proposition, that all include a runway along which the` open cans are progressvely advanced 'to a mechanlsm ormechanisms which positively engage each can my present invention, I provide a receiving ta 1 and position the same in the seeming mecha- 32 successively and at the desired intervals.

which is the vertical shaft 39 carrying at-'its`- upper end the turret 40. I have shown this Lan i to

:the frame 21 is a ,to clutch members.

The chain 34 passes around and is driven by the sprocket 35 mounted on the'.sha ft 152 and positioned to effect deliveries at the proper oint. The shaft 152 1s driven from the shagY 56 by means. of the chain 153 passing around sprockets 154 and 155 von said shafts, res ectively.v

Mounte in the forwardly-projecting arm 3 6 of the standard 21 are the frames or brackets 37 and 38, suitably. journald 1n turretiproyided with four substantially semicircular recesses or `pockets 41 r41,v equidis.

tan-tly spaced apartandjiy each of a size and ation to y receive and reasonably soulignaN snug contain a round can bodyof certain imensions. The shaft 39 isintended to'be intermittently rotated in" the same direction through. arcs of 90 each, and when in a condition of rest one of said ,recesses or pockets 41 is in position toreceive a ca n body. from-the'run-way 33 and another 1spositionedeimmediately above th'e vertically reciprocable platform 30 and therefore 1mmediatel below the chuck 24.

Suitab y. journaled iny the lower art of shaft 42 upon w ich is mounted aclutch which comprises the usual fast: and loose members 43 and 44, thedatter Y in the lform of a pulley driven from thes aft 27 by'means of a 'belt\ 45 passingf' around said pull -member 44 and around a pulley 46 onthe s aft 27. This clutch is Jop- Y erated by means of alever 47, pivoted/at 48 through a oke49 at the endthereof and adated to En d d h ictionay en' gef an isengage t e 'lelie lever 47 is yieldingly held in clutch-engaging position by means, ofa spring-50. Y 'f 52 on fa short shaft 53, the latter car pinion 54 in mesh with al gear-55 on in the lower .part of the frame 21, mannerthe shaft 56 is rotated. Keyed or' end' ofthe' shaft` 56 is the earn-block 57, provided with ancccentric run-way 58 in whlch travels the roller'f at theflower end of the vertically reciprocating rod or stem 60, at the upperj meer e oscillated in the usual manner' horlzontally and in thisr end oflwhich the platform 30'is mounted. I twill be a parent that upon rotation of the cam-block $7 the rod or stem 60 will be vertically reciprocated to fraise and lower the `platform 30, and, that 'the raisin and lower- -Y ing operations may be-'so'time as 'to effect time the turret .40 has been ,the same each brought -to a condition of rest after movement thereof through an `arc of 9001 and having in this manner positioned a can body on said-platform 3 0 with atop or cover positloned above the same in a manner which will be hereinafterdescribed.

In each of the recesses or .pockets 41 41 of` the turret. 40 )I providea substantially semicircular vspring or spring-clip 61 tov yield ingly engage the can body delivered into said recess or pocket and retain the same therein while in vtransit to the platform 30, yet not interfere-with the raising-of the can ody with said platform. A guide-strip 62 also serves to' insure retention of the can delivery of said body upon the platforml 30, it -is engaged by the 'semi-circularly recessed member 63wh1ch is at the same time a positioning 'ands a' truing orstraightening member, mounted at th'e'end of the sliding rod 64 and adapted to yieldingly compress the u per end o lthe can body between what may` e termed semi-circular dies with sulicient force to true or straighten the same,

so that a perfect 'seam may be formed by the eration, lbut yieldingly, 'as stated',`

member (i6-the operating` cam surface be-- ing shown in dotted lines.

As this truing or present invention, the above abridged descriptlon of its construction and operation isthought to be s uiiicient, although it may be added that a tension espring 67 returns the rod vand lever to initial positions after operation of vsaid lever by the cam 66` The cmu-block 57 also carriesthe roller 68 which rejects into the guide- .or run-way 69 in f the lock 70.A This/block vided with a horizontal way within which its'the bar'71 along which said block is slidable It will 'be apparent that upon rotation of the cam-block 57, thev block -.70 will be reciprocated. -On the upp faceV of tlie'fblock 70, Iv moult a rack 72 the teeth of. which mesh with the teeth 73 (see dotted linesfFig. 11)v ofv what may betermed a double-sector gear 74 loosegupon the shaft '39a^ Itwil l be-appa'rent, therefore, thatreciprocation ofthe rack 72, in the manner described,- will ca'use Oscillation of the doublebody in the pocket 41, and immediately upon i lstraightening device forms-no part of the 70 is also proiy and which is provided with four peripheral notches. eipiidistantly disposed and each adapted to receive a key on the rod or stem (30. This key S0 is'so positioned that when the, stem G0 is elevated to raise the platform $30, it has passed into one of the peripheral notches in the disk 79 and holds the shaft 39 against rotation. releasingsaid shaft when lthe platform 30 is lowered after the seaming operation. The shaft -39 being vieldinglyv clamped ybetween the; braking leaf-springs S1 (Figs. l, 2 and 8), it willA be apparent that as the clutch member 75 is rotated iu one direction by reciprocation of the rack 72, the shaft 39 will be rotated through an arc "of 900. rotating therewith the turret -10 and thereby carrying a can body to the platform 30, whereas upon rota.- tion of the clutch member 75 in the other direction. upon the return stroke of the rack 72, the braking springs 8l will hold the shaft against rotation and the clutch inember 70 will be raised to an extent sutticient to cause the teeth thereof to clear the teeth of the lower clutch member 75, which pass thereunder `to positions for rengagement therewith for further rotation of the shaft 39, at the proper time, through another arc of 90.

lhlounted upon and supported by the bracket 37 and the table 32 is the frame 82 which carries the elongated shallow casing S23. The upper plate Si of this casing is provided with an orifice. within which is mounted the ring which is slightly greater in internal diameter than the tops or covers which are to be applied to the can bodies. The machine shown and being described s adapted for the heading of so-called round cans, and it will be understood that in connection with a machine for the heading of solcalled square cans, or cans -other than round 1n shape,the internal configuration of the ring -S would corre` spend with the general shape or outline of the can head. In this ring 85 are mounted a plurality (preferably four) of posts or rods 86 8G so positioned aste ret-ain in stacked or superposed arrangement a supply of can tops or covers 87 (Fig. 7). The lower plate 88 of the casing 83 is provided with a larger orifice-large enough to permit the free passage therethrough of a top or coverbridging which are the bars 89 S9 whichsupport the stack 87 of covers.

Reciproeable Within the casing 83, in a suitable runway, is the bar 90 which is pro-. vided with an edged plate 91 so positioned as to pass between the bottom cover of thek stack 87 and the cover next above thesame, the end of the bar 90 then engaging this bottom cover and(v in its forward movement sliding the same from underneath the pile or stack to supported position upon the substantially semi-cylindrical member of the turret 40 which forms a lart of the receiving pocket for the can bo ies, whereby, when said turret has been rotated through an are of 90, the cover is positioned above a can body which has just been delivered to said turret, and after further rotation of said turret through another are. of 90, said cover is carried with the can body into the seaming mechanism in the manner heretofore described, the remainder of the stack of covers being supported upon the bar 90 during this advancing operation and dropping upon the supporting bars 89 89 after Withdrawal of the bar 90 upon its return stroke of reciprocation.

This cover-feed mechanism is actuated from the shaft 92, suitably journaled in brackets 37 and 38, at the lower end of which is mounted the gear 93 the teeth of which are in mesh with the teleth 9st of the other segment of the double-sector gear 74 ou the shaft. 39, whereby the shaft 92 is oscillated upon oscillation ofthe double-sector gear 7st in the manner described. end of the shaft 92 is mounted the lever-arm 95 adapted through the connecting-rod 96 to reciprocate the frame or block 97- upon oscillation of said sha-ft 92. 3 Depending from the bar 90 is the pin or post 98, and pivoted to the frame or block 97 is the hooked lever 99 yieldingly pressed to position to engage the pin 98 by the compression spring 100. In the absence of a body interposed to obstruct or prevent operation of the hook of the lever 99, it will be apparent that upon reciprocation of the frame or block 97 in one direction, the bar 90 will be advanced to feed a can cover to position on the turret At the upper 40, said bar being returned to initial position by means of the block 97 between which and the hook 99 the post 9S is held when being reciprocated.

As hereinbefore Suggested, one of the principal features of the present invention is the provision of mechanism for preventing the feeding of a cover from the stack S7 thereof in the absence of a can body being delivered by the 'chain 34 from the run-wayl 33 to one of the recesses or pockets 41 of the turret 40. I therefore render the hookedlever 99 inoperative in the absence of an advancing can body by providing a reciprd which comprises the arms 116 and 117,the

eating member 103, slidable in 'a suitable"- guide-Way in the frame or'bracketf82, having its end recessed to receive the pin or post 98 and an inclined or beveled face 104 upon which travels the hook. of the lever 99 when 'these parts are in the relative 4positions in- It will be apparentthat `dicated iniFig. 5. when the parts are in, these positions, 'the engaging edge of the hook of thelever 99 A;

will travel along the inclined or beveled face 04 of the member 103 and' not engage the pin or post 98, in Whichcas'e the bar 90 vvill not be reciprocated andno top or-.cover will In an arm 105, forming apart of vor suit-V ably securedto' the frame of the machine, is pivoted 'a bell-cranky lever comprisingfthe arms 106 and 107 in which are socketed the arms or rods 108jand. 109trespective1y.' To

the rod 10,9'is secured the block 110, to'vhich is pivotedthe bar 1,11 secured on the rod l1 12 which rojects into the 'run-Way 33 and carries at t e end thereof a head 113 in the pathy of movement of the advancing can bod-V ies and adapted to be engaged` thereby. The

rod 112 passes lbetwe'aen the` guide-bai' 114 of i said run-Wayfand 'the'base thereof, .and when can body, thebell-crank lever will be rocked Vin a direction tomove the rod' 108 in the di' rection of the. hooked lever 99 (I 4ig.5). Pivoted at 115 is another bell-crank lever end -of the latten being' provided with a slotted head 1184 in the slot oflyvhieh is' adapted to travel a'pin. or post-119, at lthe end of the rod 108.l The end ofthe arm 116 ment of the head 113 on the rod 112 by an y of said lever is pivoted to an extension 120 of the reciprocating member 103, and it will therefore be apparent that upon out- Ward movement ofthe rod 109, upon engagefrom -the p ost 918 and thereby 'permit saidpost to be engagedby the' hook-of the lever 99. Therefore,-When a can lbody is being ad vancedto the turret 40, the bell-crank levers Will-be actuated to permit engagement -betv'veen the hookof the leve-r 99 and Vthepost 98, anda top or cover will be fed to the' can body being positionethbut unless a can body is being advanced, .the member 103 will re'- main so positioned as to'p-revent engagement betweenA said hook andsaid post, and in `such case no top. or coverv will turret 40. l

As is to be'inferred'from what I havev hereinbefore stated, it' is' just as 'desirable that in case the supply of tops or covers in no can lbody be Vdelivered to the 'turret 40 landgtheno'e -tfrtheY seamingmechamsm.- To

providelfor this feature of operation,

mount in suitable bearings inthe frame'of the-machine averti-cal shaft 121 upon whichA isr mounted the loose collar 122 carrying the varm 123 at the endA ofrwhich is mounted the'A 'pin olf post 12,4. -This l pin or ppsft 124fi's designed tobenormallyipositionedinetha path 'of movement` oa-can coverbeing .advanced from. the stack 87- to the turret 40,V

vvhereby it Will bei'forced:.romfsuch-fpathp by the' passing top `or; e'over and. through such `movement do c 'ertaln work, as hereinturned to itsinitial' position after the. passage of each'to v.or cover, and while'asuitable spring mightbe interposed for this purpose, itl will bevapparent thatA in-"overtional Work Would ibe imposed upon `the Vcoming the' .resistanee of this spring add-ipin or post and. upon the passing canr cover Whichactuates the same, and this additional resistance to thefre'e lmovementofsaidtop o r cover might be sucient to deiect finalmovement of the same and prevent'its( ialproper positioning on the turret 4:0, or it might even result `ina slightdl'istortionjof Ithe metal of the cover, 's'u'cient to prevent the formation of a perfect seam in the heading mechanism.- I' therefore mount at the upper end of the shaft 121 a collar. 125, keyed or'otherwise suitably secured t'o said shaft, from which'projects airarm `126 havinga head 127, said head being provided i Witha' sloil 128 in which is adjustably mountd the downwardly projectingpin 129 which' is p'ivoted in` the arm 123. l Projecting in the vother `direction from the collar is the arm' 130,x at thei'end ofwhi'ch ispivoted f the pav'vl 131- and is provided'a pin -132 I vvhich constitutes a stop against which said pawl is yiel'dingly held by means of a coilspring 133 (Figsr2 and 8`). The opposite endiof said 'pa'Wl is provided'- with tapered v 'or beveled faces 134 and 135, and ,this end is so positioned (as shown in Fig.jf5)" that W it lies .in'thepath ofV movement of thepin 98. When the pin 98 is advanced, in feeding a top or cover tothe turret, it will engage the tapered face134 of the pawl 131,

and. as'- this paWl is held by the pin 132 spondingly rocks the arm 123 to 'position the pin 124thereon inthe path Aof--movement of operation, the pin 98will have clearedthe end of the ,.pawl 131, which-,is returned to its original' or initial position upon moveadvancingtop orcover.' 'In its return moveagainst 'oscillatory movement in thi's dire'ction, the arm Will berocked, thereby rockin-g the arm 136 which, in turrn, correr vthe can cover being advanced.' During this l be delivered to the 1251 ment of` thejpin 124 under action of the ment,`the pin 98- will again impinge against the end of vthe pawl 131, but asthis end o'f tion, it will be swung-clear ofthe returning pin .and restored to operative position under action of the spring 133. It will be seen,

therefore, that as an advancing top or cover strikes the pin 124 and rocks 4the arm 123, the shaft 121 be rocked.

At the lower l end -of the shaft 121 is keyed or otherwise suitably .secured the col-` lar 136 in which is mounted the projecting rod 137, and keyed or-.otherwise suitablyV secured to the turret shaft 39 is the fourtooth ratchet"P 138. Loosely mounted on the shaft 92 is a lever to the arm 139 of which is pivoted thel pawl 140 yieldingly retained in position to engage a tooth in the ratchet' 138 by means of the coil-spring 141. To the other arm 142 of this lever is secured the rod 143, the other end of which is sc- `cured to the clutch-operating lever 47,

wherefore oscillation of the arm 142in one.

direction will operate through the lever 47 to release the clutch 43-'44 andv thus termin-ate actuation of both body and cover feeding mechanisms, although the seamin .hausted, and no `cover can be advanced by lthe bar 90, obviously the awl 140 will not be withdrawn, but will engaged byV a tooth of the ratchet 127, in which event the lever which .com-prises the arms 139 and 142 will -be actuated to release all lfeeding mechanisms in the manner described, and

no can will be fed to the turret 40.

Y As the clutch members 43 and 44 are held in engagement under action of the spring,

50, it will be app-arent that unless the lever which comprises the arms 139 andy 142 is locked or checked in its releasing position the clutch will again and `prematurely become effective, and on this account I loosely mount upon the shaft 121 a collar 144 projecting from which is the lever arm 145 which is provided with a recess or hook 146 near the end thereofadapted to receive and engage a pinv 147 projecting upwardly from the lever arm 139. A spring 148, in tension 'between said arm 145 and an arm 149 .carried at `the `end of the lever arm 142,

eHects yielding engagement between the hook 146 and the pin 147 when said arm 142 has been oscillated to A release the clutch 43-44, so that both the can and coverfeeding mechanisms are retained invreleased and inoperative conditions until manually released at the desired time through the swingi" ing ofthe handle 15.0 with whichthe other end of the lever 145 is provided.

From the foregoing, it will bey apparent that I rhave provided a device adapted to be made a part of certain types of can heading machines, in which both can bodies and can tops are automatically delivered to and assembled in the'.seam'ing mechanism, which, in the absence of a can body being delivered to and positioned in said seaming mechanism, .will insure against thedelivery of'a can top or cover therefor, and which, fui thermore, in the absence lof a. can top or cover being delivered for superposition upon a can body, will automatically' check deliveries of can bodies. i v

Many modifications of minor details of my improved assembling and feeding devices for can heading machines will doubt*- less readily suggest themselves to those skilled in the art to which itv appertains, and I therefore do not desire to limit my invention to the specific construction herein shown and described.

vI claim as new and desire. to secure by Letters Patent: y i
